[0002]

[Prior Art]

 As this type of continuous press machine, there is, for example, one constructed as shown in FIG. That is, both or one of the pair of upper and lower press surface plates 11 and 12 (the upper press surface plate 11 in the illustrated configuration) can be urged by the press actuators 13 ... In addition, a drive pulley 14 rotatably driven by a drive motor 20 is provided on the front side of the press surface plates 11 and 12 in the direction in which the molding material is conveyed, and a driven pulley 15 is rotatably provided on the rear side. The endless conveyor belt 16 provided between the two pulleys 14 and 15 is configured to have a circular orbit along the pressing surfaces 11A and 12A of the press stools 11 and 12. Then, the material to be molded 30 is sandwiched and pressed by the press plates 11 and 12 via the conveyor belt 16, and the material is interposed between the material to be molded 30 and the pressing surfaces 11A and 12A of the press plates 11 and 12, respectively. The conveyor belt 16 is driven to rotate by the rotation of the drive pulley 14 by the drive motor 20, and the material to be molded 30 is conveyed while being pressure-molded and continuously molded. The conveyor belt 16 has a so-called flat belt shape, and is formed of a metal such as stainless steel with a smooth surface on the side in contact with the material to be molded 30.

[0003]

[Problems of the prior art]

 However, in the conventional configuration as described above, when the adhesive force of the material to be molded is strong, the material to be molded may be adhered / fixed to the conveyor belt and may not be separated, which causes molding failure. There was a problem.

[0004]

[The purpose of the device]

 In view of the above circumstances, the present invention provides a continuous press device capable of preventing a molding material from adhering to a conveyor belt and preventing a molding defect due to the molding material adhering to the conveyor belt. For the purpose of providing.

[0005]

[Means for solving the problem]

 In order to achieve the above object, in the continuous press device according to the present invention, an endless belt formed of a material to which a material to be molded is hard to adhere is orbited in a circular orbit along a material side of a conveyor belt along a press surface plate. It is provided and configured freely.

[0006]

[Example of device]

 Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a side view corresponding to the configuration of an embodiment of a continuous pressing device according to the present invention. In the illustrated continuous press machine 10, a pair of upper and lower press stools 11 and 12 are vertically arranged to face each other, and the upper upper press stool 11 can be moved in the vertical direction by a plurality of press actuators 13. There is. A drive pulley 14 that is driven to rotate by a drive motor 20 is provided on the front side (the left side in the figure) of the upper and lower press stools 11 and 12 in the direction in which the material to be molded is conveyed. Each side (right side in the figure) is provided with a driven pulley 15 which is rotatable.

A stainless belt 16, which is an endless belt, is stretched between the drive pulley 14 and the driven pulley 15, and the press plates 11 and 12 are positioned in the circular orbit of the stainless belt 16. The orbit is arranged along the pressing surfaces 11A and 12A of the press surface plates 11 and 12 (the orbit of the stainless belt 16 is restricted by the pressing surfaces 11A and 12A). Pulleys 17 and 18 are rotatably provided on the upper side of the drive pulley 14 and the driven pulley 15 on the upper press platen 11 side with a predetermined space therebetween, and are provided outside the pulleys 17 and 18 and the stainless belt 16. A separation belt 19 which is an endless belt is stretched around the belt with a predetermined tension.

The separation belt 19 is made of a material such as PTFE (polytetrafluoroethylene) resin, which is hard to adhere to the material to be molded by the press machine and has good releasability, and is made of glass cloth woven with glass fiber as a core material. It is impregnated and coated to form a smooth flat belt, and its orbit is regulated by the stainless belt 16, and adheres to the outside of a portion of the stainless belt 16 along the pressing surface 11A of the press platen 11 of the press belt 11. It is supposed to do. Similarly to the upper press platen side 11, the lower press platen 12 side is separated between the pulleys 17 and 18 and the stainless belt 16 which are arranged below the drive pulley 14 and the driven pulley 15, respectively. A belt 19 is stretched around, and its orbit is in close contact with the outside of a portion of the press platen 12 of the stainless belt 16 along the pressing surface 12A.

Thus, in the continuous press device 10 configured as described above, the stainless belt 16 is orbitally driven by the rotational drive of the drive pulley 14 by the drive motor 20, and the separation belt 19 driven by the stainless belt 16 is rotated. The material to be molded 30 is introduced between the upper and lower press stools 11 and 12 from the right side of the middle, and the upper press stool 11 is urged by the actuators 13 ... The material to be molded 30 is sandwiched between the boards 11 and 12, and the material is conveyed by the stainless belt 16 while being pressed and continuously pressed.

Here, the pressing of the material 30 to be molded by the upper and lower press stools 11 and 12 is performed via the stainless belt 16 and the separation belt 19, and the conveyance drive by the stainless belt 16 is performed by the separation belt. It will be done via 19. At this time, the separating belt 19 and the material to be molded 30 are not subjected to a force that particularly hinders the movement, and the stainless belt 16, the separation belt 19 and the material to be molded 30 are separated from each other in the pressing region by the press surface plates 11 and 12. After moving in an integrated state without moving relative to each other (without causing slippage) and passing through the pressing position by the press surface plates 11 and 12, the separation belt 19 is separated from the material 30 to be molded.

With the above configuration, even if the material to be molded 30 has high adhesiveness, the separation belt 19 in contact with the material to be molded 30 does not easily adhere to the material to be molded 30 and has good releasability. It is easy to separate without adhering or sticking, and it is possible to prevent the occurrence of molding failure due to the material 30 to be molded being adhered to the conveyor belt. The material of the separation belt 19 is not limited to PTFE, and any material such as polypropylene may be used as long as the material to be molded is difficult to adhere and has good releasability.

[0012]

[Effect of the device]

 As described above, according to the present invention, even if the material to be molded has high adhesiveness, it will not adhere to the conveyor belt. Occurrence is prevented.
